Big D was teaching his son how to make sure the world can't hurt him or those he cares for by means of BOMF, and she ended up leaving him because of it.

Inasmuch as any reason has ever been revealed for her leaving D-man, it was due to his hunting angels and scaring Li'l E in the process. You even linked to that strip, yourself, earlier in this thread.

But what's wrong with exposing a child to such things?

There's no direct harm from it. The child isn't damaged or hurt in any way by such actions. It only causes the child to grow up stronger faster. Instead of being pampered, he's exposed to the importance of war against enemies from an early age. As a result, he won't grow up thinking the world is a place of rainbows and sunshine, where no one would ever DARE hurt him or his loved ones.

Throughout this arc, Big D was shown teaching Lil' E how to be strong and proactive in life, instead of being weak and always on the backfoot, which is a lethally dangerous level of ignorance and pacifism.

If anything, NOT teaching children how to be aggressive against their enemies is bad parenting, since it makes them grow up weaker.

Exposing kids to excess violence does cause damage. PTSD is a thing.

If your kids need to be trained as warriors, guess what is a stupid thing to do? Not teaching them how to discern what and whom actual threats are. Going after the wrong enemy leads to wasted energy, which you can't afford to do in a fight if you want to win.

It is useful to have a reputation as someone who can kick ass, but if you do it just for the sake of it, you appear vulnerable and lacking in judgement. Why vulnerable? Because you're a loose cannon who is liable to make huge mistakes. A more patient person who avoids wasting any energy will seek to settle conflict peacably and therefore reserve their forces for when they are needed. Such a person will also treat their underlings well, because no one needs underlings who betray you at the last minute, who sell you out, or who undermine your efforts via sabotage or negligence.

What bugs me though, so she technically IS a witch, which sort of means the villagers were right in a sense. Now, the question is, "are we supposed to accept witches in our society", which honestly, I don't know.

Ok, if you don't have the answer to this in a blink, I'm going to present you:
"The burn-the-witch-guidelines"

Is she different?
yes- leave her alone
no- leave her alone
Are you afraid of her and feel the need to strike first?
yes- leave her alone, coward
no- good. Maybe try to get to know her better.
Is she dangerous if you put her or her beloved to danger?
yes- leave her alone
no- leave her alone
Are you sure she's hurting you or others?
yes- call the police
no- leave her alone

Anyone get any impression on how long ago this strip was supposed to have taken place? There aren't any real timeframe indicators. It could just as easily have been a hundred years ago or more. That's probably intentional, of course.

Any consideration of "witches" has to be based on what "witch" is defined to mean in any given context. In some fiction, a witch is something one becomes; in others, it's simply what one is.

For example, the witches and warlocks in "Bewitched" are a specific type of magical being, like elves or nymphs or any number of other such beings who existed in the Bewitchedverse, entirely distinct from humans (or "mortals"). As are the witches and wizards of the Harry Potterverse (although they're apparently not, and don't consider themselves to be, non-humans). It's innate. It's how they're born. It's what they are.

That's not at all the same as an ordinary human/mortal (Willow from "Buffy the Vampire Slayer," for instance) becoming a witch or warlock by learning how to use the innate magical energy of the universe, much less by making a pact with Satan OSLT.

In the contemporary real world, of course, some people self-identify as witches because they practice a particular belief system. Other people label as "witches" anyone who doesn't practice their particular belief system. And so on.

What bugs me though, so she technically IS a witch, which sort of means the villagers were right in a sense.

Just because she can turn them to stone does not mean she's necessarily a witch.

well, back in old salem days, it was believed the witches had sex with the devil (after dancing around naked in the full moon light). so....if you are a single mom, and you have a kid with horns.....well, let's just say, there will probably be some gossip about your sex life.

but then one has to wonder why one would have sex with the devil, if not to acquire satanic powers. especially since she does seem to have magical powers, but has never been shown as satanic, or at all evil - so she apparently neither needs nor wants his powers. of course, the devil has always been known for his charm...._________________aka: neverscared!

But what if she is a Power in her own right? Lilith, after all, is often said to be the mother of the Lilitu--Mesopotamian demons--so it wouldn't be unreasonable to think of her as a goddess or demi-goddess. As such, would it really be all that surprising that she sees the Prince of Hell as an equal with whom she could have a meaningful relationship? It may well be that she's only looking for a peer, not for magical powers bought via a deal with the Devil._________________I am only a somewhat arbitrary sequence of raised and lowered voltages to which your mind insists upon assigning meaning

I do believe she is, Persephone given her colours are the colours of spring and her powers revolve around turning people "back to the earth" also her mean tempter when provoked enough. That and she has been repeatedly shown to be kind and gentle and a far more caring soul than if she was Lilith or any number of other fallen her concerns would be more... manipulative or else dark and twisted in off ways. Not to say that the devils that have been shown do not act in a human way, but most of those that have been shown are towards former allies or they are freshly turned or else have been humanized in some way. In any event, should be interesting to see what really tore them apart, likely the Devil's overreaction to what happened here and his full change from Guardian of The Underworld into Ruler of hell.

But should maybe leave the interpretation of the Artist's interpretation of the modifications of being roles and they way they have changed over time into the modern era... Least till we see The Devil and Persephone's wedding which i think we will see.
